Modern civilization depends largely on energy. Without it, our lives would be reduced to the level of a caveman\'s. We would have nothing to power the equipment we rely on to get on with our daily lives. Life would in a way come to a standstill without energy. Without wood, we would not even be able...
As the scientific world progresses and the over-consumption of fossil fuels continues, scientists, environmentalists, and businessmen alike seek alternate forms of energy production and usage. One such alternative is viable through fuel cells. Fuel cells can power cars, trucks, and buses without emi...
Nuclear Power Alexandra Fynke ISP 207 Entering the twenty- first century, six billion people inhabit the earth. A number that is expected to double in a hundred and twenty years, yet only 4% of that world population lives in the Untied States. Even though the Untied States is only 4% of the ...
This article talks about how the hydrogen economy will be coming. There are a lot of obstacles that they must surpass to form a hydrogen economy. In the year 2003, President George W. Bush announced a 1.7 billion research program to develop a vehicle that would make the air cleaner and use less oil...
There are many ways to produce electricity but unfortunately not all of them are clean and safe. Luckily here in Canada we have clean and safe alternatives to things like the burning of fossil fuels. We are the largest producer of hydropower in the world. Hydro energy is electricity made using water...
Nuclear Power has produced more controversy than any other energy technology. Because nuclear reactors are fueled by and produce highly radioactive material, the risks they pose are more apparent. \"Two major accidents, at Three Mile Island in 1979 and Chernobyl in 1986, have increased public concer...
Stacy Jer Sept. 5 ¡®01 Period 6 When you look at our world today, do you see a future of hope or a future of despair? Why is it these days, that whenever you sit down to read the newspaper, watch the news, or listen to the radio, it seems as if most of the ...
Our Energy Supply Have you ever thought about how we get the energy to run the things we take for granite every single day? There are many sources of energy that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is clo...
Energy is one of the most fundamental qualities in our lives. Almost everything in the world is run by energy. We need electricity to turn on the lights, gas to power our cars, and energy to give us heat to warm our homes. Today, we are totally dependent on an abundant and inexhaustible supply of...
Coal Power Currently America's main source of electric energy is coal, which accounts for 1.97 PW per year or 52% of America's electric energy. We are currently extremely dependent on it for a number of different reasons. Coal is a reliable source of energy. Which is very abundant in th...
We get energy from sunlight, wind, nuclear plants, and damns... However, most of the points that we use come from fossil fuels. There are three primary fossil fuels: coal, oil, and natural gas. These are composed of carbon, hydrogen, nitrogen, oxygen, and sulfur. Carbon is the major element in fossi...
Acid Rain The concept of acid rain is often misunderstood by the vast majority of the world, however, most realize that it is a problem. The burning of fossil fuels has released pollutants into our earth's atmosphere. Once airborne, the pollutants form acidic compounds by combining with w...
Electricity is extremely precious and valuable. Our town should be lucky to have it. In other cases we shouldn\'t use too much of it either. There are lots of different ways of creating electricity.
